NHTSA Complaint #11433556 — 2014 MAZDA CX-5

While driving on an urban road and going over a slight bump, heard a clunk in the left rear wheel well. Pulled over and off road to investigate the situation. Was unable to see any particular cause in the rear suspension. However a small piece of corroded aluminum fell onto the ground from up inside the wheel well. The vehicle was taken to a repair shop and the diagnosis was that both aluminum rear shock mounting plates were corroded. The left rear shock had separated from the mounting plate. The service station was unable to locate-acquire new mounting plates, hence had to have both shocks completely replaced on Aug. 19, 2021. I believe this problem represents a risk to the public, a potentially serious safety issue. I have a photo of the repair invoice and imagine the repair shop can confirm the basic problem. I located a Mazda email contact address and emailed them regarding the issue this evening.
